Online videos will not play

Hi,

Recently I've been having trouble getting videos to play online. Youtube works fine, but almost every other online video won't play, namely megavideo as that's what I use most often. I press play but the video window goes black or blank, and it just sits there and doesn't buffer.

I have a Macbook Pro and have the most recent flash player, java, etc. It's not a problem with my browser, because videos don't work on either Safari and Firefox, and nor do they work on my desktop computer using the same internet, leading me to believe that the internet is the root of the problem, even though it's reasonably fast and I've never had this problem with it before.

Can anyone help me out?

Cheers.
